points 1.You will get used to it very soon if you come.get used

to：过去经常做的事情（但是现在已经不做了）这里的to是不定式，因此后面要跟动词原形用法：usedto+V（原形）Iusedtoplaywithmyfriendsafterschool.过去放学后我常常和朋友们一起玩。Key pointsbe used to do/doing：有两种用法用法一：beusedtoV（原形）事物被用于这里的to是不定式，used是被动形式Woodisusedtomakepaper.木材被用来造纸。用法二：beusedtoV-ing/sth表示人习惯做某事/东西这里的to充当介词，因此后面要跟动名词或者名词Mr.Liisusedtowashinghisfacewithcoldwater.李先生习惯于用冷水洗脸。Key
